refactor: Enhance Cursor file modification logic with robust error handling

- Replaced awk-based file parsing with more precise sed replacement
- Added comprehensive validation checks for file modifications
- Improved error logging and handling during file processing
- Updated user guidance message to include restart and potential reinstallation instructions
- Maintained existing script functionality with more resilient modification approach
